Anyone in here have the new size pulleys for the C30 and know what boost you're hitting at redline? I swapped over to the new pulleys and just got a chance to open it up... Boost on the old ones was ~11.5 and on the new ones I'm seeing between 9 and 9.5. Hoping this is due to the pulley change and not another bad blower, but it does whine very loud....
